Referring to the Figures, in which like parts are indicated with the same reference numerals, various views of an exemplary audio digital recording and playback device configured to conveniently store and play audible messages pertaining to specific golfing techniques and situations according to principles of the invention are shown. An exemplary device is a portable handheld audio recording and playback device for use by golfers in recording and playing back tips with respect to strategies for play of holes on a golf course. The exemplary device has a rectangular handle which is approximately 1″ (depth)×0.5″ (width)×2.5″ (height), with a speaker housing of 1.2″ (diameter)×1.1″ (depth) mounted atop the handle. The front of the device includes a variety of category (i.e., golf activity) selection switches, a visual status indicator (e.g., LED), an opening for a built in microphone, and openings for a built in speaker. A control for record and playback modes is provided on the back of the device. A volume control with an on/off setting is side-mounted. Internally, the exemplary device contains digital recording and playback components and circuitry configured to be controlled by the externally mounted control buttons. The device is battery powered.

Referring now to FIG. 1, a front plan view of an exemplary audio digital recording and playback device 100 configured to conveniently store and play audible messages pertaining to specific golfing techniques and situations according to principles of the invention is conceptually shown. The device 100 includes a handle 160 and a speaker housing 110. The handle 160 houses circuitry, batteries and related components to allow the device to store and play audible messages pertaining to specific golfing techniques and situations according to principles of the invention. The speaker housing 110 includes a plurality of apertures 115 to facilitate transmission of audible output from a speaker contained therein.

A plurality of controls 120-140 are provided on the handle 160 of the exemplary device 100 as means for selecting categories for recording and playback. In a preferred implementation, the controls 120-140 are momentary contact switches. Each switch is associated with a category of play, such as Full Swing 120, Pitching 125, Chipping 130, Sand 135 and Putting 140. The controls 120-140 are operably coupled to record and play circuitry contained within the handle 160 of the device 100. While five momentary contact switches are shown along the front surface of the handle 160 in FIG. 1, the invention is not limited to such types, quantities or positions of switches. Other types, quantities and positions of user controls may be utilized and are intended to come within the scope of the invention.

Advantageously, the preferred controls 120-140 are sized and spaced to allow an operator wearing a golf glove to easily manipulate them. In a preferred implementation, the center of each control is spaced d2 approximately at least 0.5 inches from center of each adjacent control, and the space d1 between adjacent edges of adjacent controls is approximately at least 0.25 inches. If the play/record mode selector switch 170 of the device 100 is set in play mode at or prior to commencement of a round of golf, then an operator may conveniently access a pre-recorded message by pressing one button, i.e., the easily-accessible switch corresponding to the category of play. It obviates navigating through a complex user interface and series of stored messages to access a particular recorded message.

As discussed above, in an exemplary embodiment, the categories include types of swings, including Full Swing 120, Pitching 125, Chipping 130, Sand 135 and Putting 140. A full swing is a complex rotation of the body aimed at accelerating the club head to a great speed. It consists of a backswing, a downswing, and a follow through. Full swings generally apply to tee and fairway shots. Pitching is an approach shot from between approximately 20 yards to 100 yards from the green intended to land the ball onto or near the green. Pitch shots are usually hit with any club from a six iron to a lob wedge. Chipping is a low approach shot where the ball makes a shallow flight and then rolls out on the green. Chips are made with a less lofted club than a “pitch” shot in order to produce the desired flatter trajectory. Sand refers to a bunker shot, which is played when the ball is in a bunker (i.e., a sand trap). It resembles a pitch and is played with a sand wedge, a club with a wide base configured to skid in the sand. The bunker shot differs from other golf shots in that the ball is not touched by the club head, but is lifted with an amount of sand. Putting refers to the practice of hitting a golf ball on a green using a putter. During putting, the ball rolls on the ground, never becoming air-borne. While the foregoing categories are preferred, the invention is not limited to them. Other terminology for the categories, and other categories of golfing, may be utilized in addition to or in lieu of any or all of the aforementioned golfing categories, without departing from the scope and spirit of the invention. Illustratively, categories named according to parts of the course or categories assigned meaning by the operator may be utilized and come within the scope of the invention.

An indicator 145 is provided on the handle of the exemplary device 100 to signal status of the device. Any visible indicating element suitable for signaling the status of a portable battery operated electronic device may be utilized. By way of example and not limitation, a light emitting diode, incandescent lamp, visual display screen, or any other visual display means may be utilized.

A microphone 150 is provided in the handle 160 of the exemplary device 100 to convert sound into an electrical signal. In a preferred embodiment, an electret microphone, which may include an integrated preamplifier is utilized. However, other microphones, including, without limitation, condenser, piezo, carbon, ribbon microphones or plunger coil microphones may be utilized.

A suspender component 105 is provided on top of the speaker housing 110 to facilitate hanging the device 100. The suspender component 105 may comprise an eyelet, u-shaped band, hook or other component through which a hook, support strap or the like may be engaged to suspend the device 100 from an object.

Referring now to FIG. 2, a back plan view of the exemplary audio digital recording and playback device according to principles of the invention is provided. A play/record mode selector switch 170 is provided. The switch is operably coupled to record and play circuitry contained within the handle 160 of the device 100.

A cover 165 for a battery compartment within the handle 160 is also provided. The cover 165 is removable to allow access to the compartment. In a preferred embodiment, the cover 165 is slidingly engaged by the handle 160. The battery compartment is configured to contain one or more batteries, such as (but not limited to) three AA size batteries. The contained batteries supply electrical power to the record and play circuitry contained within the handle 160 of the device 100.

Referring now to FIG. 3 provides a side perspective view of an exemplary audio digital recording and playback device according to principles of the invention is provided. A volume adjustment switch 155 is operably coupled to the record and play circuitry contained within the handle 160 of the device 100. The switch 155 is configured to control volume of the speaker contained within the speaker housing 110. The switch 155 has high, low and off positions. By way of example and not limitation, the switch may be configured as a slide switch with three discrete settings (e.g., high, low and off), or as a fader (i.e., slide potentiometer) infinitely adjustable from high to off settings, or as a rotary potentiometer infinitely adjustable from high to off settings.

Referring now to FIG. 4, a high level block diagram of an exemplary electronic subsystem of an audio digital recording and playback device according to principles of the invention is shown. The electronic subsystem includes circuitry and components to store and play audible messages pertaining to specific golfing techniques. The circuitry and components interface with the switches 120-140, indicator 145, microphone 150, volume adjustment switch 155 and play/record mode selector switch 170 of the device. The electronic subsystem preferably includes an integrated digital sound circuit 410, such as, for example, a Winbond® ISD 170 ChipCorder®, which provides an integrated single-chip, multi-message voice record and playback device, and suitable interface and control circuitry. A record duration may be preset within a determined range, such as 20 to 60 seconds. A sampling frequency may be set within a determined range such as 4 kHz to 12 kHz. The integrated circuit 410 may include an on-chip microcontroller, oscillator, microphone preamplifier with Automatic Gain Control (AGC), nonvolatile memory, one or more filters, a speaker driver/amplifier, volume control and current/voltage output, an analog to digital converter (ADC), a digital to analog converter (DAC), and other components. Electrical power is supplied by one or more batteries 430.

The play/record mode selector switch 170 is configured to set to Record and Play modes. The circuit 410 is configured to cause the LED 145 to flash when Record mode is selected. The circuit 410 is configured to commence recording when a momentary contact switch 120-140 corresponding to a category, such as Full Swing 120, Pitching 125, Chipping 130, Sand 135, or Putting 140 is selected. Additionally, the circuit 410 is configured to cause the indicator (e.g., LED) 145 to illuminate steady, without flashing for the duration of recording. Audible sounds received through the microphone 150 during recording generate analog audio sound signals. Optionally, the analog signals may be pre-amplified and filtered by the circuit 410 before further processing. An analog to digital converter (ADC) within the circuit 410 converts the analog signals to digital audio data according to a determined sampling frequency. The circuit 410 then encodes the data into a determined compressed or uncompressed format. The circuit 410 then stores the encoded audio data in a memory location allocated for the selected category. A location in memory allocated for each category, such as Full Swing 120, Pitching 125, Chipping 130, Sand 135, or Putting 140, may be defined by a start address and an end address in the available memory. As an alternative to reserving and allocating certain memory locations to certain categories, the circuit 410 may store message data in the next available memory location and associate that location, whatever it may be, with the selected category. The circuit 410 stops the recording event at the end of the determined recording duration, upon which the circuit 410 causes the LED 145 to flash again to indicate that recording is completed.

The circuit 410 is configured to play a message previously recorded for a category, when the play/record mode selector switch 170 is set in Play mode, the volume control 155 is set to an audible playback volume level, and a switch 120-140 for a category of interest is momentarily selected. The circuit 410 is configured to access stored message data corresponding to a selected category from the memory location allocated to the selected category. The circuit 410 is also configured to decode the stored data. Then, a digital to analog converter (DAC) in the circuit 410 is configured to produce analog output signals from the decoded data. An amplifier in the circuit 410 is configured to amplify the analog signals. The circuit is also adapted to transmit amplified signals to the speaker 420, which converts the analog signals to audible output.

The invention is not limited to the above-describe exemplary circuit. Rather, the above-describe exemplary circuit is intended to represent a broad range of digital recording and playback components and circuitry configured to record, store and play messages for determined categories of golf in accordance with principles of the invention. All such circuits and components are intended to come within the scope of the invention.

Referring now to FIG. 5, a high-level flow chart of an exemplary recording and playback process 500 according to principles of the invention is conceptually illustrated. First, the device is set to either record or playback mode, as in step 505. To record a message, the play/record mode selector switch 170 is set to Record mode and the indicator LED 145 flashes, as in step 5 10. The operator then selects a category (i.e., a golfing activity), such as by pressing a momentary contact switch 120-140 corresponding to the category, e.g., Full Swing 120, Pitching 125, Chipping 130, Sand 135, or Putting 140 categories, as in step 515. When an activity is selected, the indicator LED 145 will illuminate steady, without flashing for the duration of the record event, as in step 520. Audible sounds received through the microphone 150 during the recording period will generate analog audio sound signals. Optionally, the analog signals may be pre-amplified and filtered before further processing. An analog to digital converter (ADC) then converts the analog signals to digital audio data according to a determined sampling frequency. The digital audio data is then encoded and stored in a memory location allocated for the category, as in the recording step 525. The recording event will automatically stop at the end of the determined recording duration, as in step 530, upon which the LED 145 will flash again to indicate that recording is completed, as in step 535. The steps of recording a message may be repeated for the same or another category in a like manner, as in step 540. In a preferred embodiment, prior saved message data is replaced with new message data.

To play a message previously recorded for a category, the operator moves the play/record mode selector switch 170 to Play and sets the volume control 155 to a desired playback volume level, as in step 545. Then the operator selects an activity such as momentarily pressing a switch 120-140 for the category of interest, as in step 550. The stored encoded data corresponding to the selected activity is accessed from the memory location allocated to the selected category and decoded. A digital to analog converter (DAC) produces analog output signals from the decoded data. The analog signals are then amplified and transmitted to the speaker 420. The speaker 420 converts the analog signals to audible output, as in the play step 555. The process of playing a message may be repeated for the same or another category in a like manner, as in step 560. If the desired message has been played and no repeats or additional messages are desired, the process ends, as in step 565.

While an exemplary embodiment of the invention has been described, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. With respect to the above description then, it is to be realized that the optimum relationships for the components and steps of the invention, including variations in order, form, content, function and manner of operation, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
